摘要
针对设计尖速比对水平轴潮流能叶轮动力特性的影响问题开展研究工作。基于叶素-动量理论建立叶轮动力特性仿真模型,以叶片数量分别为2、3、4的叶轮为对象,考察设计尖速比对叶轮的功率系数的影响。研究结果表明:设计尖速比越大的叶轮,其最大效率也越高;叶片数量多的叶轮,其功率系数略优于叶片数量少的叶片。结合分析结果,给出了水平轴潮流能叶轮的设计尖速比的选择建议。
The influence of designed tip speed ratio （TSR） on the hydrodynamic performance of horizontal marine current turbines is studied. To validate how designed TSR works on the power coefficient, a series of turbine models are established based on the blade momentum theory with blade number of 2,3,4 and designed tip speed ratio ranging from 3 to 8. The simulation results show that a better power coefficient is presented with higher designed TSR and the power coefficient with more blade number is better than that with less one. At the end of this paper, a suggestion on selection of designed TSR is given.
